I've read a lot of different topics and comments from people who agree with maestro. There are many arguments in support of philosophical themes, prequel directions, and reimaginig the Alien universe. There are also many arguments against, but for, returning to the franchise's roots.
Regardless of this, most people agree on one thing - the Alien no longer scares. And here comes a terrible mistake of thinking - "If the Alien no longer scares, then it is already cooked". It is necessary to abandon the Alien and go to other, new things. For what and why? To maintain the status of horror?
My questions:
1) Is it necessary to maintain the direction of horror?
2) Should Alien be scary?
My answers - no.
1A-Problem) I'm more than sure that the Alien franchise can exist outside of the horror genre. Look at Prometheus and Covenant. Isn't it the horror elements that make these film feel awkward? The elements of horror limit the films and force them to use the same tropes. Oh, a couple of people separated from the team, got lost and got eaten. Oh, shower scene... Oh, some guy went to take a piss, and another decided to sniff a weird mold. Oh, some guy exposed a suspicious android, but he won't tell anyone and will go one-on-one with the robot. What could go wrong? Oh, this is a horror film, but there is so many survivors in the end. Let's sweep them all under the carpet (Vickers, Janek & Co, no name crew of Prometheus and Covenant).
1B-Solution) Avoiding the dumb horror tropes doesn't mean avoiding the "tasty filling". Trilobite extraction, Engineer vs trilobite, Fifield's attack, birth of a praetomorph and neomorph, eradication of Engineers - are breathtaking and beautiful scenes. Keep them. Keep blood and gore but avoid the tropes of horror. The Cabin in the Woods nailed it.
2) Should Alien be scary? Can Alien be scary? This is all subjective. Alien must do terrible and inhuman things, but It depends on your attitude to the Alien. If you like Alien and you are curious about what it can do, then you will not be scared anyway. It is easy to evoke feelings of disgust. But the feeling of fear - no. Especially if you are in the Alien universe for several decades. I just want to say - if you want to get a scary beast, then you don't get one. Because you will not be able to repeat your first experience with the Star Beast. But you can get a smart and unstoppable beast that will crush everything in its path. Or you can get a drooling space cockroach ... and then you get scared!
The problem is not the Alien. You don't have to try to reimagine the beast. But maybe you should try to distance yourself from the horror genre and try to create a more exploratory, detective, adventure aspect.
